drive shaft probs

[mud4b]

ive got a lux double cardon on the rear of the zook..

what i need to know is

do the knuckles at either end need to line up
or do the balancers need to be aligned?

[bazooked]

if u mean yokes yes they do.

[mud4b]

YES I MEANT THE YOKES..

COOL

[mud4b]

thanks bazooked...can someone back this up

[rock hopper]

yes they are ment to be lined up .
most of the time if the uni's where fitted right . the grease nipples should be all on the same edge ......
but if some one fitted the uni ass about it won't line up ..
if you send some close up pics . i should beable to tell you yes or no .....

[bazooked]

yes nud that is right i have been doin tail shafts for bout 11 years....

for a regular uni jointed shaft, you're all right, the yokes should be aligned to prevent driveline vibration. a double cardan joint, however, is a Constant Velocity joint, and misalignment of the yokes with the uni joint at the other end will not make a scrap of difference to driveline vibration. If the shaft has been dymanically balanced as a unit, it should be reassembled the way it came apart to maintain that balance, but for a front shaft it's not usually an issue unless you're building a tourer, in which case you probably wouldn't have (a) a zook (b) a hilux CD shaft in the back.

u are getting vibs in ya zook?

i dont think u will get rid of them with the dc cos it is ment to have no angle on the diff end (all the angle is ment to be taken buy the dc joint)

and in a zuk u cant point the diff at the tcase so there is always goin to be an angle at the diff

my next zuk i am just goin to run a normall d shaft and see if that helps it

why not? it is a matter of getting the angle of the spring perches right, can be fine tuned with castor wedges if necessary. the shaft angles will change a bit with suspension movement obviously and I appreciate the rear shaft on zooks is pretty short, but it should be doable, to get it to perform acceptably on the road.

u would have to move the rear diff back on the drivers side and leave it stock on the passanger side (although it might wana pull to the left a bit ) to get the diff to point at the tcase

driver drop output + centered diff

ok, nobody mentioned you had a lux axle in the back. change it to a bundera axle with an offset diff, or run double cardan joints both ends of the trailshaft (probably not room to do that?)

[mud4b]

plenty of room in the back as it is extended.

the diff is angled towards the flange on the t-case but as mentioned it is offset and the diff is centred.

its only over 60 ks that it vibrates...

ill get it balanced and see how that goes.as i have shaved the flange on the dc side so the sierra flange nut will fit through it.

a sierra tailshaft will fit but only on a moderate lift .even with spacers.
